La Garrotxa: Researchers Pinpoint Youngest Volcanic Area In Spain
2012-07-24 12:52:30

Brett Smith for redOrbit.com - Your Universe Online Although volcanic scientists are able to approximate the age of lava flows, determining the exact timing of each of a volcano´s eruptions has proved difficult in the past. A joint research team from the Universitat Autònoma de Barcelona, University of Girona, the Catalan Institute of Human Paleoecology and Social Evolution (IPHES) and other organizations has looked to establish a chronology of eruptions in the...

Australia's Great Barrier Reef Gets A Little Help From Volcanic Eruptions
2012-07-20 06:50:48

redOrbit Staff & Wire Reports - Your Universe Online Have you ever wondered how the Great Barrier Reef came to be? Research conducted by Queensland University of Technology geologist Dr Scott Bryan indicates that volcanic activity in the Southwest Pacific could help to save the Great Barrier Reef, but it could also be what caused it to form in the first place. Dr Bryan and colleagues studied the westward flow or rafting of pumice after volcanic eruptions in Tonga in 2001 and...

Pumice has long been recognized as the original, natural pozzolan–used by the Romans in their impressive 2000+ year-old concrete structures. A landmark study just released by the University of Utah details the performance, longevity and strength advantages of pumice as a concrete-fortifying pozzolan–advantages that are critical for today's high-performance infrastructure and industrial needs. The pumice pozzolan used in the study–HessPozz–was sourced from Hess Pumice...

Smaller Volcanoes Could Cool Climate According To Satellite Research
2012-07-05 16:33:57

A University of Saskatchewan-led international research team has discovered that aerosols from relatively small volcanic eruptions can be boosted into the high atmosphere by weather systems such as monsoons, where they can affect global temperatures. The research appears in the July 6 issue of the journal Science. Adam Bourassa, from the U of S Institute of Space and Atmospheric Studies, led the research. He explains that until now it was thought that a massively energetic eruption was...

New Geology articles posted online ahead of print June 15 Orange-like rocks in Utah with iron-oxide rinds and fossilized bacteria inside that are believed to have eaten the interior rock material, plus noted similarities to "bacterial meal" ingredients and rock types on Mars; fine-tuning the prediction of volcanic hazards and warning systems for both high population zones and at Tristan da Cunha, home to the most remote population on Earth; news from SAFOD; and discovery in Germany of the...

Potential Eruption In Iceland Could Pump Acid Into European Airspace
2012-06-12 15:11:11

A modern recurrence of an extraordinary type of volcanic eruption in Iceland could inject large quantities of hazardous gases into North Atlantic and European flight corridors, potentially for months at a time, a new study suggests. Using computer simulations, researchers are investigating the likely atmospheric effects if a “flood lava” eruption took place in Iceland today. Flood lava eruptions, which stand out for the sheer amounts of lava and sulfurous gases they release and...

Warning Signs Of The 2011 Axial Seamount Eruption
2012-06-11 02:53:32

A team of scientists that last year created waves by correctly forecasting the 2011 eruption of Axial Seamount years in advance now says that the undersea volcano located some 250 miles off the Oregon coast gave off clear signals just hours before its impending eruption. The researchers´ documentation of inflation of the undersea volcano from gradual magma intrusion over a period of years led to the long-term eruption forecast. But new analyses using data from underwater hydrophones...

Villarrica
2014-08-19 11:03:54

Villarrica, also known as Rucapillán, is an active stratovolcano that is located in Chile and is protected within Villarrica National Park. This volcano is one of five known volcanoes to have a lava lake within its crater and it often produces strombolian eruptions that contain lava flows and incandescent pyroclasts. It is one of three volcanoes that occur along the Gastre Fault Zone, along with the less active Quetrupillán and Lanín volcanoes. During the Valdivia Interglacial, it...

Mount Price
2014-08-19 10:51:33

Mount Price is a stratovolcano that is located in British Columbia, Canada. It is part of the Garibaldi Ranges and reaches an elevation of 6,732 feet, rising above the lake at its western side and the land and other volcanos surrounding it. In the past, this volcano has been known by many names including Red Mountain, Fissile Peak, and Clinker Mountain. It and many other volcanos are protected within the Garibaldi Provincial Park, which also features rich habitats with abundant wildlife....

Hoodoo Mountain
2014-08-19 10:23:50

Hoodoo Mountain is flat-topped stratovolcano that is located in British Columbia, Canada and is part of the Northern Cordilleran Volcanic Province and the Pacific Ring of Fire. It is thought to be potentially active and was named for the needle like projections that protrude from it. These lava spines, or hoodoos, reach heights of 492 feet, making it the most distinct mountain in that area of the Boundary Ranges. Hoodoo Mountain is primarily flat-topped, which led volcanologist Jack Souther...

Socompa
2014-08-19 10:02:27

Socompa is a complex stratovolcano that can be found at the border of Chile and Argentina, reaching an elevation of 19,852 feet. This volcano is best known for its avalanche debris deposit, which have formed the Monturaqui Basin on its west side, the most noted example of this type of deposit in the world. It is a difficult volcano to visit, taking at least a day by vehicle traveling from the north or the west. Socompa is also known for the microbial ecosystems that occur near grasses at its...

Mount Erebus
2014-08-19 09:49:48

Mount Erebus is an active volcano that can be found on Ross Island in Antarctica. It is the second largest volcano in Antarctica, reaching a height of 12,448 feet. Sir James Clark Ross discovered it in 1841 in mid-eruption and named it and another volcano Mount Erebus and Mount Terror, after two of his ships. The first people to climb the volcano and reach its summit were part of Sir Ernest Shackleton's party, including Professor Edgeworth David, Jameson Adams, and Dr. Eric Marshall. Mount...
